You don't have to reveal anything to anyone. This is about you recognising and accepting you, not anybody else.
You are out of this relationship. You are free. The constraints, now, are in your own mind, they are your responsibility. You can walk away, if you can grasp that you did nothing wrong, you were not weak, your actions made sense in the context they were in, and you don't have to talk to anybody about any of it until you feel like it.
This is yours, now. You are in charge. You are responsible for looking after the part of you that screams, and keeping her calm and comfortable. You do that by doing what you'd do with any screaming child: hold them, reassure them, make sure they know they are loved, listen to them, understand them. You don't do it by telling them they're weak, by being angry at them. Can you see how that would make the screaming louder and more frustrated?
You've been abused. There is an angry part of you because of this. And so there should be. That's the voice of your healthy boundaries, shouting at you.
This is very important, OP: There is nothing wrong with you. Anybody who tells you there is, get them out of your life. That's been how you've let yourself down, by allowing them back, but everything you did within those relationships was a normal response to abuse. Every single thing. You are completely normal. Accept yourself as this, and work from that basis. Then, when some unqualified bod rocks up, who you know wants to upset you, and says 'You have a disorder', you can calmly say 'Er, no, I don't.' and that's all the drama it will cause you.
